ron'rABLE AND KNOCKDOWN STORAGE-BIN.

Specification of Letters Patent. Patented uly 22, 1919.

Application filed J 1115 22, 1918. 'Seria1No.246 201.

To all whom it may concern:

Be itknown that I, MAXWELL B. FITCH,

a citizen of the United States, residing at Corona, in the county ofRiverside and State of California, have invented new and usefulImprovements in Portable and Knockdown Storage-Bins, of which thefollowing is a specification.

My invention relates to portable and knock-clown storage bins andconsists of the novel features herein shown, described and claimed; I

My object is to provide footings, interlocking wall plates, and wallplate supporting bars, so that a temporary bin'may be constructed of anydesired ground area and of any height, used the desired length of time,and then torn down, to be re-set up in another place and of any desireddifferent area and height.

My present invention is an alternative or modification of the inventionshown in my patent dated May 7, 1918, No. 1,265,442.

' Figure 1 is an elevation of a knock-down storage bin embodying theprinciples of my invention. 7

Fig. 2 is a' vertical sectional detail upon an enlarged scale and takenupon the line 22 of Fig. 1.

Fig. 3 is a fragmentary horizontal sectional detail upon the line 3-3 ofFig. 1 and upon an enlarged scale.

Fig. 4 is 'a perspective detail showing a fragment of the bin.

In preparing to construct a storage bin in accordance with theprinciples of my invention, the ground will be leveled to form asuitable floor forthe material to be stored, and the footings 1 are thenarranged upon the floor in a circle surrounding the storage area. Thiscircle may be comparatively large or small, as desired.

The footings 1 each comprise a base block 2 of wood or other material, abase plate 3 of metal secured to the upper face of the base block, and aretaining flange 4 extending upwardly from the base plate 3. I A tier ofwall plates 5 is placed end to end upon the footings 1 inside of theflanges 4, there being interlocking hooks Sand 7 upon the vertical edgesof the plates, the hook 6 of one plate interlocking with the hook 7 ofthe next plate so as to make an endless band surrounding the storagearea.

A row of supporting bars 8 is then placed upon the upper edges of thewall plates 5.

The supporting bars 8 are curved to make the desired circle and saidbars are Z-shaped in cross-section so as to form seats 9 for receivingthe upper edges of the plates 5 and seats 10 for receiving the loweredges of the next tier of'wall plates 11.

The tierof wall plates'll is identical with the tier of wall plates 5except that the band formed is slightly smaller.

, Then a second series of wall plate supporting. bars '12 is applied tothe upper edges of the wall plates 11. The wall plate supporting bars 8and 12 may be substantially alike,

and if they arealike it is only necessary to turn them end for end sothat the seats 9 will open upwardly and the seats 10 will opendownwardly.

Then a third series of wall plates 13, identical with the wall plates 5,is applied, with their lower edges fitting in the seats 9.

Then a third series of wall supporting bars 14, identical with the wallsupporting bars 8, is applied to the upper edges of the wall plates 13,and a fourth series of wall plates 15, identical with the plates 11, isapplied to the supporting bars 14, and so on to the desired height.

In constructing the wall plates 5, 11, 13 and 15, notches 16 are cut inthe corners of the plates where the ends of the seams 17 would come, sothat the ends of the seams are cut away to clear the wall supportingbars 8, 12, 14, etc.

My knock-down storage bin may be used for temporarily storing grain atthreshing time and it may also be used for storing sand, plaster,crushed rock, coal, and other material in doing contract work Where thematerial is to be stored for a short time and then used and the bins nolonger needed, and

"the bin may be used for many other purposes, depending upon thelocation and the requirements.

Various changes may be made without departing from the spirit of myinvention as claimed.

I claim:

1. A series of wall plates, and interlocking hooks formed upon themeeting edges of the wall plates and connecting the plates together toform a continuous band; the plates being notched out at the ends of theseams formed by the interlocking hooks.

2. A knock-down bin comprising a series of rectangular wall plateshaving the edges of their adjacent vertical sides rolled upon themselvesto form an interlocking joint, said series forming a continuous band anda series of Wall plate supporting bars 2- shaped in cross section toengage the upper ends of said wall plates and the lower ends of theseries of wall plates immediately above the lower series of wall plates,the upper ends of the vertical joints being cut away whereby thesupporting bars may form a continuous smooth band joining the upper andlower edges of adjacent series of wall plates.

3. A knock-clown bin comprising a plurality of series of wall plates,each series of said wall plates having their vertical edges interlockingto form a continuous band, a series of supporting bars Z-shaped in crosssection engaging and holding in place a pair of adjacent bands, saidbars forming a continuous band, the ends of each bar abutting the endsof adjacent bars, said bars being arranged in break-joint relation withthe interlocking joints of the Wall plates. 1

4:. A knockdown bin comprising a plurality of series of wall plates,each series of said wall plates having interlocking vertical edges andforming a continuous band, adjacent bands of wall plates being arrangedin break-joint relation to each other, and a series of supporting barsZ-shaped in cross section supporting adjacent bands of wall plates andforming a continuous band, the ends of said bars abutting the ends ofthe adjacent bars and the joints in the said band of bars being inbreak-joint relation MAXWELL Q FITCH.
